Abstract
The utility model relates to a novel motor bearing, a shaft bushing and a bearing base adopt a mode of center support, the number of the oil ring is increased by two, the utilizing efficiency of the lubricating oil is improved, meanwhile, a rolling bearing is added to enable the precision and the stability of the operation the motor rotating shaft to be improved, and one part of axial thrust can be effectively endured, an inner bore alloy of the shaft bushing is changed from a common bearing alloy into a special high-temperature alloy, and a bearing exterior oil supplying device is omitted. The utility model has characteristics of high adjustment capability, good lubricating effect, low cost, long service life and high stability and safety during high speed operating of the motor.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of New-type electric machine bearing.
Background technology
Bearing is the crucial parts of a class in power plant's accessory, and motor bearings is a big class of bearing, and its center technology is the cooperation of bearing shell and the cooling of bearing.The structure such as the accompanying drawing 1 of existing common electric machine bearing: mainly comprise bearing shell (1), be inlaid in the oil ring (2) that contacts with the machine shaft cylindrical in first groove of bearing shell (1), cast in the bearing metal that the bearing shell endoporus contacts with rotating shaft, support the bearing pedestal (4) of bearing shell, bearing shell (1) adopts bilateral pair of spherical support mode to cooperate with bearing pedestal (4), oil ring (2) quantity is 1, and bearing metal (3) is the plain bearing alloy.Bilateral pair of spherical support mode is limited to the unbalance regulating power that the amount of deflection owing to axle causes in this structure, and oil ring (2) has only 1, and the lubricating oil utilization ratio is low, and needs outside fueller, will increase cost like this.Plain bearing alloy (3) performance of bearing shell endoporus is general.Said structure is very big to the normal influence in useful life of bearing, even therefore influences the useful life of whole motor.
Summary of the invention
The purpose of this utility model is a kind of self-adjusting ability height of design, high lubricating effect, security performance height, the New-type electric machine bearing that cost is low.Scheme of the present utility model is so to realize:
A kind of New-type electric machine bearing, comprise bearing pedestal (6), be loaded on the bearing shell (5) in (6) in the bearing pedestal, be located at the oil ring (7) in first groove of bearing shell (5), the quantity of described oil ring (7) is two, the center of bearing shell (5) contacts with bearing pedestal (6), and a side of bearing shell (5) is provided with a rolling bearing (8).
As preferably, described bearing shell is provided with endoporus in (5), and alloy of cast is special high temperature alloy in it.
The utility model changes bilateral pair of spherical support mode of original motor bearing shell into the center support mode, increased the quantity of oil ring (7), increase a rolling bearing (8) simultaneously, change bearing shell (5) endoporus alloy into special high temperature alloy by the plain bearing alloy, deducted the outside fueller of bearing.This structure has been improved the unbalance regulating power of bearing shell (5) to causing owing to shaft deflection, the quantity that increases oil ring (7) has then improved the utilization ratio of lubricating oil, the rolling bearing that increases newly (8) improves the precision of machine shaft operation and smoothness, and can bear a part of axial thrust effectively, the casting properties of special high temperature alloy improves the fail safe of bearing shell (5) under the situation of motor high-speed cruising than the casting properties height of plain bearing alloy greatly.The alleviating of bearing shell (5) weight makes the load reduction of axle, also saved cost simultaneously, and the subduction of outside fueller makes cost reduce more.The utlity model has the regulating power height, high lubricating effect, the smoothness during the motor high-speed cruising and safe, cost is low, characteristics such as long service life.
Description of drawings
Accompanying drawing 2 is a kind of structural representations of the present utility model
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings 2, a kind of New-type electric machine bearing comprises bearing pedestal (6), is loaded on the bearing shell (5) in (6) in the bearing pedestal, is located at the oil ring (7) in first groove of bearing shell (5).Describedly be embedded in first groove of bearing shell (5) and be two in the quantity of the oil ring (7) of machine shaft cylindrical contact, lubricating oil can also form the oil film lubricate between two oil rings (7), and the utilization ratio of the lubricating oil of rotating shaft also is enhanced like this.
Bearing shell (5) and bearing pedestal (6) adopt the center support mode, unbalancely have a self-adjusting ability more flexibly for what caused by shaft deflection.
One side of bearing shell (5) is provided with a rolling bearing (8), rotation precision and smoothness in the time of improving the machine shaft high-speed cruising effectively, and bear certain axial thrust.
The alloy of pouring into a mould in bearing shell (5) endoporus is special high temperature alloy, also can guarantee the bearing safe handling under the situation of machine shaft operation generation high temperature.
Claims (1)
1. New-type electric machine bearing, comprise bearing pedestal (6), be loaded on the bearing shell (5) in (6) in the bearing pedestal, be located at the oil ring (7) in first groove of bearing shell (5), the quantity that it is characterized in that described oil ring (7) is two, the center of bearing shell (5) contacts with bearing pedestal (6), and a side of bearing shell (5) is provided with a rolling bearing (8).
